Abstract

A fabric including within its construction a first elongated electrical conductor crossed by a second elongated electrical conductor, the conductors being normally biased apart at a crossover point of said fibres with an air gap between them, whereby application of pressure in a direction substantially normal to a plane of the fabric causes the conductors to make contact. The fabric may be woven, knitted, non-woven or plaited. The fabric can be used as a pressure sensor, switch or other sensor.

Description

FIELD OF THE INVENTION

[0001] The present invention relates to methods of constructing one or more pressure activated electrical switches or sensors in fabric, in the preferred embodiment as integral elements of a single fabric sheet.BACKGROUND OF THE INVENTION

[0002] Electrically conductive fabric sheets are known in the art and are described, for example in the applicant's earlier British patent application 2,339,495. The known conductive fabric sheets typically comprise two conductive layers separated by an insulating layer which can be bridged upon application of pressure on the conductive layers. Although such fabric assemblies can function well, there are inevitable drawbacks with having to have three or more fabric layers, including additional cost, fabric thickness, need to maintain alignment between the various layers, movement of the layers during use and so on.SUMMARY OF THE INVENTION

[0003] The present invention seeks to provide an improved conductive textile. According to an ...
